Matching a flat Alumacraft 1648 2006 against a deep vee Alumacraft Competitor 175 CS 2013 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Alumacraft 1648 2006 at 16,0 ft versus Alumacraft Competitor 175 CS 2013 at 17,7 ft. Weight tells a clearer story for trailering families: the Alumacraft Competitor 175 CS 2013 tips the scales at 1 285 lbs — 1 000 lbs less than the Alumacraft 1648 2006 at 285 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 150 hp, the Alumacraft Competitor 175 CS 2013 has a 115-hp advantage over the Alumacraft 1648 2006's 35-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Alumacraft Competitor 175 CS 2013 is rated for 6 passengers, while the Alumacraft 1648 2006 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Competitor 175 CS 2013 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft 1648 2006 comes in at 8 lbs per hp versus 9 lbs per hp for the Alumacraft Competitor 175 CS 2013. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
